Headlight adjustment mechanism

[Betty]

Happy New Year everyone! 

Does anyone have a guide or advice re. how to get the manual adjustment mechanism out of an old pair of headlight units and into a new pair? My old ones have lost all their silvering on the plastic bits and the bulb-holding halo has popped off the back of one too so I thought I might treat the beast to a new pair of shiny eyes.

I've tried to do this in the past and I just couldn't get them to budge at all, and I really don't want to break them as no new ones come with them fitted.

It's for a Ph1.

from memory rotate the body of the adjuster a3rd of a turn then disengage the ball from the socket.

Anti-clockwise? I'll have another go when my new lights get here but last time I tried I just couldn't get them out at all! 

Thank you
